OKLAHOMA CITY (AP) — Officials prepared Saturday for a winter storm that was expected to move into Oklahoma late Sunday and on into Arkansas, making Monday morning’s commute dangerous.

Two to 4 inches of snow were expected in the higher elevations of the Ozark Mountains in northeastern Oklahoma and northwestern Arkansas and sleet or freezing rain was forecast in southeastern Oklahoma and southern Arkansas.

Meteorologist Karen Hatfield said she didn’t expect significant ice accumulation that would cause extended power outages, but the mix of snow, sleet and freezing rain would likely create hazardous driving conditions.

“It’s going to be, quote unquote ‘bad’ compared to what we’ve seen so far this year. I think the main headache it’s going to cause, because the snow is going to fall early Monday, it’s going to probably impact the Monday morning commute,” said Hatfield, who works in the National Weather Service’s Tulsa office, which covers eastern Oklahoma and northwestern Arkansas.

Transportation officials in both states said crews were getting ready for the storm.

Randy Ort, spokesman for the Arkansas Highway and Transportation Department, said workers spent Friday and Saturday “pre-treating” roads with chemicals that help dissolve precipitation that would otherwise collect on the pavement as it falls.

“We told our people ‘Enjoy the weekend to the best of your ability,’ and ‘You’re on call,”’ Ort said.

“Midnight Sunday, early Monday morning, we expect to have crews out and ready for whatever comes our way,” he added.

Similar measures were taken in Oklahoma, said Cole Hackett, spokesman for that state’s transportation department.

“The last few days and throughout the day today (Saturday), we’re making sure all our trucks are up and maintained and all our equipment is ready to go and all our people are rested and ready to go,” Hackett said.

The department had 70,000 tons of salt and 70,000 tons of sand ready to be applied to roads, he said.

The storm was not expected to approach the severity of two blizzards that struck in Oklahoma during the first two weeks of February last year, Hatfield said, but is the first storm of significance in the region this winter.

Hatfield said the storm should begin moving out of the region by Monday afternoon, and clear to partly sunny skies were expected by Tuesday.
